Systems, methods, and computer readable media for sharing awareness information

Abstract

Systems, methods, and computer readable media for sharing awareness information are provided. A non-aware electronic device can require awareness information including, for example, information about its environment or information about its status within its environment, in order to perform a particular device operation. When the non-aware device lacks an awareness component for detecting the required type of awareness information, the non-aware device can establish a communications path with an aware device that includes such an appropriate awareness component. The aware device can share the required type of awareness information as captured by its awareness component with the non-aware device. The distance between the non-aware device and the aware device can be less than a threshold distance to ensure that the shared awareness information is relevant to the non-aware device.
